The ergotec High Bass is the extension of the Bass stem and offers additional features to maximise your riding comfort. With a 45° angle, this stem allows for a more upright riding position that contributes to a more comfortable and relaxed ride. The High Bass is designed to meet the needs of riders who prefer a more upright position. This is particularly beneficial for riders who want to cover longer distances or those who are looking for a more comfortable option for their MTB or E-MTB.

Despite the more comfortable riding position, the High Bass has the same stability as its counterpart, the Bass stem. It still offers a high load capacity of up to 140 kg (bike + rider + luggage) to meet the demands of sporty rides. With its robust yet stylish design, it fits perfectly with your MTB or E-MTB and gives your bike a high-quality look. Whether you are going on long tours or simply looking for a more comfortable riding position, the ergotec High Bass stem offers you the possibility to increase your riding comfort.


Proven High-Quality though Extreme Strength Tests. In ergotec Test Center, all ergotec handlebars, stems and seat posts are subjected to extreme long-term tests, both individually and in combination. In addition to testing in line with European standards, ergotec also tests according to the significantly higher ergotec SAFETY LEVEL requirements.

Safety Level to Define Component Capacity. Conventional bike components do not meet the requirements which are imposed with a higher system weight. For this reason we have designed components which are specifically intended for this purpose. The ergotec XXL parts featuring Level 6 are specifically designed for these requirements, and can therefore be used without reservation at City bicycles of up to a max. permitted weight (bike + cyclist + luggage) of 140 kg.

Durability and Longevity. Carefree and safe on the road with the ergotec quality promise! Opting for an ergotec product always means opting for premium quality. Quality you can rely on for many years – it‘s a guarantee! Products under Safety Level 6+ like ergotec Bass is expected to be usable until it's end of life without any km limit unlike the lower graded products.

Ergonomical Certification ensuring Comfortable Riding. Thanks to certification as an ergonomic product and the corresponding approval procedures, ergotec demonstrates that ergonomic products reduce discomfort when cycling not just in theory, but also in practice! This benefit is proven and documented by the test certificate of the Institute for Health and Ergonomics (IGR).

Performance Meets Safety. For many years ergotec supports the world champion, World Cup winner and multiple national winner Tomas Slavik. His trust in ergotec‘s MTB components, which meet his exacting requirements, confirms brand's commitment to develop high-quality products.


All steering systems and all ergotec stems are tested without exception and are then classified with a SAFETY LEVEL. All ergotec seatposts also have a SAFETY LEVEL. Irrespective of whether you ride a mountain bike, an e-bike or a touring bike – you will always get the exact component with safety certification you need.

ergotec SAFETY LEVEL is a safety classification for steering systems and seatposts on bicycles. ergotec products have a SAFETY LEVEL of 1 to 6. The higher the level, the greater the safety. Each level has their suggested bike activity, from city to cargo.

All handlebars and stems are subjected to hard long-term testing individually and in combination. The same applies for seatposts. This testing is carried out in accordance with European testing standards or even higher demands.

No other bike handlebar manufacturer in Europe has as large a testing centre as we do at ergotec. Furthermore, our products are tested frequently at recognised independent institutions.
